B+W
B+W 72mm IR Infracolor (099) Filter
Key Features
  • Used for Infrared Photography
  • Ideal for Color IR or False Color Film
  • Blocks Short-Wave Radiation Up to 520nm
  • Full Transmission Begins at 600nm
The B+W 72mm IR Infracolor (099) Filter is mainly used in conjunction with color infrared films to block portions of short-wave radiation (blue and blue-green) up to 520nm. It reaches full transmission of radiation around 600nm, which it retains beyond the feasible sensitivity range of false-color films. By blocking the blue range with these films you are able to capture a better range of colors with more differentiation between tones. This filter still allows you to depict vegetation and plants in a unique reddish manner due to the infrared reflectivity of chlorophyll. The filter factor is highly variable depending on the sensitivity of your specific film and the lighting situation under which you are photographing in.

B+W filters are constructed from high quality Schott glass for increased optical clarity and color fidelity. They feature a brass filter ring for durability as well as jamming prevention.

Used for infrared photography with color infrared (false-color) films.
This filter attenuates short-wave radiation (blue and blue-green) up to 520nm and has full transmission of radiation around 600nm.
By blocking blue casts when using these films there is better separation of colors.
The red, orange, and pink appearance of plant life is still maintained when using this filter.
Constructed from high quality Schott glass for optical clarity.
Brass filter ring helps to prevent jamming and provides additional strength.
